Viking. Sealed burner dual-fuel electronic-control ranges in three sizes have been added to the Professional Series Custom product line. The electronic control panel combines the traditional feel of a knob with the features of an electronic display. A mirrored display appears when the controls are not in use. Other features include Sabbath mode and auto-roast, which automatically sears meats and then returns to a preset temperature for roasting, and sealed gas burners with VariSimmer, which allows for precise control at very low cooking temperatures. Select models are available with a TruPowerPlus burner for up to 18,500 BTU. Choose from 30-, 36-, or 48-inch ranges in stainless steel or a choice of 23 color finishes. 888.845.4641. www.vikingrange.com.
